Kendrick Lamar tweeted to his fans that he would be throwing a secret free concert in downtown LA, but there was nothing secret about it.

Lamar basically pulled a double-decker bus in front of Staples Center after a Lakers game and turned it into a huge street party.  Kendrick said: "I wanted to do something special that actually made a point, made a statement! Better to do it in our hometown, right after the Laker game. I've never done a surprise show like this."

The crowd spilled into the streets and exceeded the limits allowed by the city. After performing 'Swimming Pools,' 'The Recipe,' and another track, the police got rid of the crowd.
